BQ25892RTWR Description

Short technical summary and product information.

The BQ25892RTWR from Texas Instruments is an advanced I2C-controlled single-cell battery charger IC capable of delivering up to 5A charge current. It features a Switch-Mode Buck control topology and is optimized for high input voltage applications, supporting a range of 3.9V to 14V.

 

Key electrical specifications include a battery charge voltage range of 3.84V to 4.6V and a maximum charge current of 5A. The device offers high charge efficiency, reaching 93% at 2A and 91% at 3A. It also includes a USB On-the-Go (OTG) boost mode with adjustable output and a selectable boost converter frequency of 500kHz or 1.5MHz, providing up to 2.4A output.

 

Designed for robust operation, the BQ25892RTWR incorporates features such as Input Current Optimization (ICO), Input Current Limit (IINDPM), Input OVP, and IC thermal regulation. It also includes BAT temperature thermistor monitoring and an integrated ADC for system monitoring. The charger supports various input adapters and offers accurate Hiccup Mode overcurrent protection.

 

Packaged in a 24-WQFN (4x4) with an exposed pad, this surface-mount device operates within a temperature range of -40°C to 85°C. Its Narrow VDC (NVDC) power path management ensures instant-on functionality even with no battery or a deeply discharged battery.
